The model consists in the minimization of a functional dependent on second derivatives, free discontinuity and free gradient discontinuity. The competitors are piecewise C2 vector-valued functions, whose components represent the intensity of RGB channels. Keywords: Calculus of variations, free discontinuity problems, regularity, inpainting, image segmentation, Gamma convergence. MSC: 49J45, 49K20 [ Fulltext-pdf (295 KB)] for subscribers only. |
